Multi-Sig Crypto Inheritance

A discussion on how multi-signature security works for crypto assets and its applications for wealth transfer and security.

Multi-Signature Structure

• Requires multiple keys to access crypto assets instead of just one
• Common configurations:
  • 2-of-3 keys needed to access vault
  • 3-of-5 keys needed to access vault

Key Distribution Strategy

• Keys can be distributed among trusted parties:
  • Personal key (self-held)
  • Spouse/family member key
  • CPA key
  • Wealth management entity key
• Can keep majority of keys personally (e.g., 3 out of 5)

Security Benefits

• Protects against kidnapping vectors
• Allows for velocity limits on transactions
• Professional key holders (like wealth management firms) can:
  • Implement proper key management practices
  • Only sign under specific conditions
  • Set transaction limits

Challenges

• Most CPAs lack private key management knowledge
• Need for specialized education of key holders
• Requires trust in multiple parties
• Complex balance between security and accessibility

Death/Inheritance Considerations

• Creates circular logic problem:
  • Need to trust others with keys for inheritance
  • But trusting others increases security risk
• Requires careful planning for property transfer
• Need for new solutions specific to crypto wealth transfer
• Traditional estate planning methods may not be sufficient
